SPECIFICATION forming part of Letters Patent 110.659.560, daten octobere, 19Go. Application iled December 4, 1899. Serial No. 739,142. (Nomodel.)

T0 @ZZ whom, it may concern:

Be it known that 1, DIETRICH WILLIAM TIETJEN, a citizen of the UnitedStates, and a resident of Milwaukee, in the county of Milwaukee andState of Wisconsin, have invented a new and Improved Ice-Cycle, of whichthe following is a t'ull, clear, and exact description.

The purpose of this invention is to provide superior attachments forbicycles, permitting them to be employed on ice, and to this end Iprovide detachable runners for raising the tires of the bicycle abovethe ice, and I also provide a detachable ice-rim for the rear ortraction wheel of the bicycle, such rim being arranged to engage the iceto propel the bicycle thereon.

This specification is the disclosure of one form of my inventiomwhilethe claims define the actual scope thereof. Y

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters 0f reference indicatecorresponding parts in all the views.

Figure lis a side elevation of a bicycle having my improvements applied.Fig. 2 is a rear elevation thereof. Fig. 3 is a section on the line 3 3of Fig. 1. Fig. 4.- is an enlarged elevation of part of the means forsecuring the rear runners in place. Fig. 5 is a section on the line 5 5of Fig. 1. Fig'. 6 is a longitudinal section of the ice-rim, showing itin place. Fig. 7 is a plan view of the ice-rim. Fig. 8 is a section onthe line 8 8 of Fig. 7. Fig. 9 is a section on the line 9 9 of Fig. 7.Fig. 10 is a section on the line 10 10 of Fig. 1. Fig. 11 is a sectionon the line 11 1l of Fig. 1. Fig. 12 is a side view of one of the clampsfor holding the ice-rim in place, and Fig. 13 is a perspective View of atool employed in placing and displacing the ice-rim.

For attachment to the front wheel of the bicycle I provide a singlerunner 11,'(see Figs. 1 and 11,) which is rigidly connected with asocket-plate 15, and this plate is formed in each side edge with anumber of orices 16, in which are engaged the links 17 of clamping-heads18. These clamping-heads are iitted with thumb-screws 19,which engagewith the rim of the front Wheel and by which the clamping-heads 18 maybe forced inward, straining on the links 17 and securely holdltively tothe rear wheel of the bicycle.

y lution by a strap or other suitable lashing 20,

engaged with the steering-fork, as shown in Fig. 1. This runner 14therefore raises the front wheel out of contact with the ice andsupports the same, so that the steering-fork l may be directed t-o guidethe bicycle.

For supporting the rear part of the bicycle I provide two runners 2l,arranged one at leach side (see Fig. 2) and each provided withstanchions 22, preferably constructed of angleiron. The stanchions 22extend upward and are connected with each other at their upper ends toform a loop 22a. These loops are connected with the rear axle of thebicycle, as shown in Fig. 3. Such connection is effected by means ofnuts 23, which are screwed on the threaded ends of the rear axle `inplace of the usual nuts and which serve to hold the axle in place withrelation Ato the frame of the bicycle, as Fig. 3 shows'. The nuts 23have threaded extensions V23ad at their outer en ds,on which additionalnut's 24c aremounted. Fitted snugly on each extension 23a is the head25a of a screw 25. 'These screws -25 extend down inside of therespective loops 22a :and loosely through cross-bars 26, rigidly at.-

tached to such loops, as shown. Nuts 27 work on the screws 25 below thecross-bars 26, and the loops 22L of the stanchions 22 are extended overthe extension 23a of lthe nuts 23, the loops being permitted to sliderela.

tively to such nuts 23, so that by operating the nuts 27 the screws 25may be moved to adjust the position of the stanchions 22 rela- As shownin Fig. 4, the nuts 27 are set in recesses 'in the loops 22, whicharrangement enables the screws 25 to be moved up or down by the`loperation of the nuts 27, as explained. The `two runners 21 are bracedtransversely by Abars 28, extended between them and located,

respectively, at the ends of the runners. From the front bar 28 a brace29 extends forward to the crank-hanger of the bicycle to furtherstrengthen the structure. This brace 29 is detachably connected with thecrankhanger in anysuitable manner. It will be seen that by these meansthe rear runners 21 may be easily applied to and disengaged from thebicycle, and, if desired, by regulating the nuts 24 the runners 21 maybe thrown up toY theposition shown by dotted lines in Fig. 1, in whichposition the rear wheel will be permit,-

`ted to engage the ground and the runners 21 will not interfere with theoperation of thebicycle in` the ordinary manner This enf ahles the rearrunners to be applied to the contiguous ends of thestrap forming theicerim are joined to each other by a button- 31, 1

attached to one end and engaging in autorifice32` in the other end. Theendsof the'iceL rim overlap, as shown, and may be drawn into lockedposition or moved from suchposition through the medium of, ai tool'(shown: in Fig. 13) working with lips 33, respectively formed on theends of the ice-rim, preferably by striking up from the rim portions oftheV material composing the same.

tively pivoted to the ends of.` a link 35. At one end the jaws 34 areprovidedwith a screw` 36 and at the other` end: with pins 37.

loops 33, and by. working the screw 26 itlwlill; be seen that; thenecessary pressure may be:

applied to the ice-rim to etectt theobject in` view. The ice-rim` has.its edges formada-t1@ various points with orifices 38, similar totheorifices 16 of thesocket-platel. with.V which.

orifices are adapted to be engaged.clamps.` 39,'. (see Fig. 1,) suchclampsbeing similar tothe clamps of the socket-plate `15 and serving,`to-` hold the ice-rim in place.

which are surrounded by bossesl40, and; in these bosses are slidablyfitted spurs 41,. the

outer ends of whlichare pointed to engager-he; ice1(see Fig. 6) and theinner ends-of which are Aprovid ed wil h heads`42,which bearagainstithe` pneumatic tire of the bicycle-wheel, asshown; For limitingthe movement of theV spurs4-1-` 'and the bosses4OI provide each-1 boss.with` a screw or pin 43, (see-Fig. 10,) which screws. respectively fitin grooves 44formed5inithe The resiliency of the pneui-` i spurs, asshow-n.

This toolY (shown in Fig. 13) comprisesjaws 34respec- `cle-wheels, oneend ofi the rimV being; formed 1 with; antopening andthe other end-.oftheyrim Tibet `having;albutton to engage insuch-` opening, pins 37 areadapted to` be engaged withi the The ice-rim 30 is formed with a numberof openings therein, 1

in Fig. 6; but when the spurs are engaged with-.the ground the weight.which isiplaced on the spurs will cause them to yieldv inward againstthe tire, as shown at the left in Fig. 6', the spurs at the same timeengaging with the ice in such a way as to prevent the slipping ofl theice-rim. The pressure of the tire on the spu rs will cause them to bevery firmly engaged with the ice, at the same time per- 'mitting thespurs to yield suciently to avoid jarring the rider and also to avoidundue straining of` the parte of, the device.
